STAPLlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 330,950, dated November 24,, 1885.

Application filed April 17, 1882.

To all whom it may concern:

Be it known that we, JOHN D. WILBER and A. BEVERLY SMITH, citizens of the United States, residing at Towanda, county of Bradford, State of Pennsylvania, have invented a new and useful Improvement in stapling-Maphines, of which the following is a specifica- In the accompanying drawings, Figure l is a top view of the machine. Fig. 2 is a side elevation, partly sectional, through the line as m, Fig. 1. Fig. 3 is a front elevation of the machine with portions broken away to show staple forming, cutting, and driving mechanism. Fig. 4 is a detailed view of clutching mechanism. Fig. 5 shows details of the clinching mechanism. Fig. 6shows manner of driving and clinching staples. Fig. 7 is a sectional view of staple former and driver, showing grooves in former in which staple rests after being formed and in which ribs 011 stapledriver slide. Fig. 8 is a section of stapledriver with cross-head. Fig. 9 shows adj ustable plane table. Fig. 10 shows adjustable angular table.

Similar letters refer to similar parts throughout the several views.

011 shaft A is rigidly secured wheel A, of sufficient diameter and thickness to carry the proper cams in; also, wheel H, carrying mutilated gear h, for operating wire-feeding mechanism, and stud h", for operating clinching device; also, wheel I, containing spring i and bolt i also, on shaft A loosely runs the band wheel J, which, when engaged by clutch-pins t" '5 with clutch-bolt i in Wheel I, gives motion to the entire machine.

In face of wheel A, Fig. 8, is cam-groove co in which works stud 0 Fig. 2, attached to stap1e-former O. In periphery of wheel A is cam-groove a, Figs. 1 and 2, in which works stud O on staple-mandrel C The mutilated gear h on wheel H engages with pinion h, secured to gear-wheel h both running on a journal adj ustably secured by dovetailed piece it to standard if. Gear-wheel If engages with gear-wheel h, secured to shaft 9, revolving in journals 9 Fig. 1. On the other end of shaft g*is the milled wheel G, rigidly secured. Underneath milled wheel G is idler g, also milled, and running in journals 9 at proper distance from G. If desired, the journals of Serial No. 58,487. (No model.)

idler y can rest upon a rubber or other suitable spring to allow for variation in the size of wire used. Block 6 sliding in ways F, Figs. 1 and 3, has secured to its end knife 0, also ways e e, in which slides block E, having secured to it knife 0, and carrying forked arm f, sliding over scale fon ways F. The block 6 can be secured in any desired position by set-screw f 2 in ways F. The curved lever e, hinged to journal 9 by pin 6 extends through the forked arm 6 suiiicient distance to engage with pin a on wheel A. Lever e issustained in position by spring e 'resting on way F.

Stapleformer 0 slides freely in ways 0 G. On the inner faces of its forks or prongs, and extending its entire length, are grooves d d, Fig. 7, in which staple is pressed when formed, and in which ribs d d, Figs. 3 and 7, of stapledriver D work. Former G and standard O form guides, through which the staple-driver D works. On staple-driver D is shoulder 0 on which rests spiral spring 0. Orosshead B, of proper shape, containing in its upper portion the angular recess b, is attached to driver D, Figs. 8 and 8. In B works pin a,extendc. On block'e is wireguide c also pointering from projection A on wheel A. On plate 7 A is staple-mandrel O sliding in dovetailed ways formed in lower portion of standard a. On (3 is stud c, which works in cam-groove (t on periphery of wheel A. Below plate A", directly under staple forming and driving mechanism, is tablestandard L, supported by spring 70 k 76*, Fig. 2, which rests on base K. In standard L, Fig. 3, is slot 70, working over stop it", which limits the upward movement of standard L by spring 7a. The base K is made so as to form a support for the spring k and guides or ways for standard L. Attached to standard L is the clinching mechanism, (shown in its various detail in Fig. 5,) in which l is a circular groove in which clinchers Z Z vibrate around pin 1, forming common center. The lower portions of Z l contain slots Z Z through which projects a pin on the end of lever Z'. The clinchers Z l are so formed as to cross each other. Lever Z is fulcrumed at Z and extends downward, having in its lower part opening Z in which one end of lever 70 works. 70 is fulcrumed on pin 76, Fig. 2, and

engages with lower end of lever h, which is The upper end of h fulcrumed on stud k.

engages with pm h on wheel H. Theplane table, Fig. 9, designed for flat work, is attached to standard L and secured by set-screw 0. The shouldered projection on standard L, Fig. 2, enters recess 0, Fig. 9, the throatscrew m.

plate Zforming part of the table. The angular ,table, Fig. 10, fits on and is secured to standard L in a similar manner to the plane table, Fig. 9, and is intended for use in work requiring staplesto be driven through the center of a fold, as through the center of a pamphlet, the angular-shaped table being preferable for that purpose. In Fig. 4 lever '5 is fulcrumed on pin z",and carries on its upper end the plunger i On lower end of i is catch i hinged at i with 6 and is held in position by spring 1'". M is a rod sliding in standards m of, and connected at one end with a treadle or other suitable mechanism, and having secured to its other end plate m by set- The coiled spring m encircles M between supports m m holding M in proper position.

In operation motion is given the bandwheel J, which carries on its face pins #6 The rod M, Fig. 4, being drawn forward, the plate at engages with catch 2', and through lever z" thrusts plunger "5 against clutch-bolt i forcing it through wheel I and clutching against pin i. Plate 2', secured to standard a by bolt 2', contains a slot, through which plunger '5 works, and into which at each revolution bolt 11 is thrust by spring i, thereby unclutching wheel I from band-wheel J. As the rod M is drawn forward after making the clutch, the point of the catch i slips over the .edge of plate m, thereby releasing the lever 11 and allowing the plunger 2' to be forced back by the bolt i on its arriving opposite the slot in plate 6. The rod M being released, spring m forces it back to its original position, the hinge of catch 2' allowing plate m to pass readily underneath the point of 6 Should continuous motion be desired, plate m is revolved until its longer face will engage with clutch d and not pass under, thereby retaining the lever in position to keep the machine in clutch. On motion being given, the mutilated gear it engages with pinion h, which is secured to wheel h which in turn engages wheel h, giving sufficient rotation to milled wheel G to feed the proper length of wire. For different-sized staples,requiring different lengths of Wire, the necessary variation in movement of milled wheel G is obtained by changing the sizes of intermediate gear-wheel, h Gearwheels of the required sizes, having pinions h of a standard size, are attached to dovetailed blocks, k fitting in standard if. The wire '9 being fed by rotation of milled wheel G, passes through guide 6, between knives e and e, Fig. 3, passing the proper distance beyond and over the mandrel 0 At this point the stud a on wheel A enters the angular recess I) in cross-head 13, allowing spring 0 toforce driver D down firmly upon wire 9 clamping it upon mandrel G a small groove in bottom of driver ping of D, independent of action of stud a during a portion of its revolution. At this moment the pin of strikes lever e", forcing down knife 6 past knife 6 and thus severing the wire by a shear out. At this instant camgroove a operating on former O, forces it down and over mandrel 0 forming the staple, and clamping the material to be stapled between it and the table. At this point cam a in periphery of wheel A retracts the mandrel C a proper distance. At this time stud a engages cross-head B, forcing driver D down, driving the staple into and through the article to be stapled. The ends of the staple striking the semicircular anvil Z, Fig. 6, are forced outwardly over the inclined faces of clinchers Z Z. the article to be stapledis held firmly between the ends of former and driver and the springtable, stud k on wheel H strikes lever h, and through levers 70 and Z a quick upward thrust is 'given to clinchers Z l, bending the prongs of the staple outward at right angles and firmly against the article stapled.- The stud.

tween plate A and the table is maintained by stop k on base K. Staple-former G and driver D are brought down sufficiently to compress spring is in stapling the thinnest work. The spring is of sufficient strength to properly clamp the thinnest work to be stapled, and, as thicker material requires heavier clamping, this object is attained by the proportionate greater or less compression of the spring is by the varying thickness of the work inserted. The advantages of supporting the table on a spring or springs are, obviating the adjustment of the machine to each thickness of work and the liability to breakage through imperfect adjustmentor accidental insertion of any extra thickness of material, which objections attach to I every machine having a positive adjustment to its table.

The irregular V-shaped opening Z in l, in which lever It works, is for the purpose of giving the same thrust to the clinchers'l in whatever position the table may be, through having thicker or thinner material on it for stapling. This is accomplished by widening the opening 0 in proportion to the lessening of the working radius of lever 2*.

Having thus described our invention, what we claim as new therein, and desire to secure by Letters Patent, is-

At this moment, and while ITO 1. The mutilated gear h, changeable wheels h h and gear-wheel h, in combination with the milled feed-wheels G and 51, substantially as and for the purpose specified and shown.
